Q. Why does splitting if S heart sound occurs with atrial septal defect but not ventricular septal defect?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Splitting of the S2 heart sound is a common finding in patients with atrial septal defect (ASD) but not typically present in those with ventricular septal defect (VSD). Splitting of S2 occurs when the aortic and pulmonary components of the second heart sound are heard separately, usually due to their different timing.
In an ASD, there is an extra pathway for blood flow that bypasses the lungs, meaning that both pulmonary artery flow and aortic artery flow travel through the same valve before circulating throughout the body. When this occurs, it causes asynchronous emptying from the left and right ventricles which leads to slightly different timing between closure of each valve producing two distinct split sounds from each component.
In VSD however, there is often no significant evidence for asynchrony due to lack of pressure differences between both sides on a systemic level since VSD involves interventricular communication (blood flows directly between right and left ventricles). As such, there would be less splitting than what you hear in cases where pressure gradients exist within one side vs another which typically occurs when large ASDs exist causing some diversions.

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
